Peru Subnational NDVI: 10-Day Vegetation Indices and Anomalies

Peru's sub-national vegetation health is tracked through dekadal (10-day) NDVI indicators derived from NASA MODIS collection 6.1 satellite imagery. Produced by the World Food Programme (WFP), the data aggregates pixel-level observations into administrative units to provide historical averages and current anomalies.

Use Cases

• Monitoring agricultural health by comparing current NDVI (vim) against the long-term average (vim_lta)
• Identifying drought conditions using the NDVI anomaly percentage (viq)
• Weighting the reliability of regional aggregates using the n_pixels count

Strengths

• Uses NASA MODIS collection 6.1 sensor data
• Includes standardized Pcode references for administrative units
• Provides a historical baseline via the vim_lta column

Limitations

• Aggregated format obscures local-scale vegetation variations
• Fixed 10-day temporal resolution prevents daily monitoring
